I like to compare how similar or different The Machine is to current state-of-the-art LLMs. Interestingly, in this fiction, The Machine's preferred way of communicating doesn't seem to be through text, or even artificial speech. It can see almost everything, and seems capable of improving itself, but it feels "intelligent" in a way that humans or LLMs aren't. Maybe the writers thought that giving it the ability to write text or speak directly would make it "less" in many ways (less mysterious, less machine-like, less intelligent, etc.). It also gives the impression that you cannot really guess what it "thinks" or fully understand it.
I'm also realizing that most of the time, characters don't really have a "conversation" with The Machine, whereas it is a core feature of current-day LLMs. And The Machine doesn't even "create" its communication channels, it uses existing ones (phone booth, radio ...).
